Ocata Series Release Notes¶

15.1.11¶

The os_ceilometer role now includes a facility where you can place your own templates in /etc/openstack_deploy/ceilometer (by default) and it will be deployed to the target host after being interpreted by the template engine. If no file is found there, the fallback of the git sourced template is used.

New variables have been added to allow a deployer to customize a ceilometer systemd unit file to their liking.

The task dropping the ceilometer systemd unit files now uses the config_template action plugin allowing deployers access to customize the unit files as they see fit without having to load extra options into the defaults and polute the generic systemd unit file with jinja2 variables and conditionals.

For the os_ceilometer role, the systemd unit TimeoutSec value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. The RestartSec value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using the ceilometer_*_init_config_overrides variables which use the config_template task to change template defaults.

The ceilometer configuration files other than ceilometer.conf are now retrieved from upstream. You can override the repository from which these are retrieved by setting the ceilometer_git_config_lookup_location variable which defaults to the git.openstack.org.

The variables ceilometer_requirements_git_repo and ceilometer_requirements_git_install_branch have been removed in favour of using the URL/path to the upper-constraints file using the variable pip_install_upper_constraints instead.

The vars to set source_sample_interval for the os_ceilometer role are deprecated and will be removed in the Queen cycle. To override these variables after Queen, utilize the ceilometer_pipeline_yaml_overrides file.
